MACHINE FOR BOBBIN TO-BOBBI1\T SIZING.

Application filed December 16, 1927, Serial No. 240,593, andin Great Britain December 30, 1926. M

type in which the yarn is drawn off a set of bobbins or cheeses arranged horizontally in a winding frame or reel.

According to the invention the winding bobbins or cheeses are driven by frictional contact; with the periphery of a number of wheels or discs, each bobbin contacting with or resting upon a wheel or disc at one or both ends of the bobbin and each wheel or disc being engaged with two adjacent bobbins.

Fig. 9 is a detailed view partly in section of bobbin bearing.

The machine comprises a creel A in which the bobbins a carrying the unsized yarn are mounted, a sizing trough B, a heating plate or cell C and a frame D in which are mounted. the bobbins or cheeses (Z on to which the sized yarn is wound. I

The sizing trough B is mounted on a bracketE which can be moved up and down onthe pillars E by the chain c and ratchet wheele Mounted on the pillars E are fixed brackets E which support the roller B rotating in the trough B and a comb B through the dents of which the unsized'yarn passes before coming into contact with the roller'B from the reel end also showing stationary or reciprocated as desired;

The frame D on which the bobbins dl are mounted is preferably arranged at an angle as shown'in Fig. 1 so that the yarn passing to the bobbins at will be'spread out at a greater angle.

The bobbins (Z are arranged in rows across the frame each pair of rows being driven from friction discs f mounted on a shaft F extending across the machine so that there i is one shaft F for each two rows of bob-- bins the shaft extending between and below thebobbins. Two friction discs drive each bobbin and engage with discs or wheels 9 and g one at each end of the spindle G on which the bobbin ismounted. The disc 9 is formed integrally with the spindle G and the disc 9 is formed with a central bush y which screws on to the threaded end of the spindle Gr (see Fig. 6) so that the bobbin (Z is clamped between the discs 9 and g and will rotate therewith. The ends of the spindle Gr project beyond the discs and g and are carried in bearings 71, mounted in a bar H extending from front to' back of the frame. There may be any number of bars H according to the number of bobbins 61 there are across the frame.

Thebearings it (see Fig. 8) are preferably formed of compressed fibrous material to reduce the wear onthe spindle and are each formed with two transverse slots h and 72, the slot it? being deeper than the slot 71?. The deeper slot Jt receives the end of. the

spindle G when in the operative position i. e. when the discs g and g are in engagement with the driving discs f and the shallow slot [b2 is for the purpose of receiving the ends of the spindle G when the bobbin (Z is lifted out of the'operative position. The

preferably the same throughout the frame. Each hearing it serves for the ends of the spindle G of two adjacent bobbins (Z and it is therefore preferably divided by the plate if to position the bobbins transversely.

Instead of being driven by friction discs the bobbins may be driven by rollers ,1 contacting directly with the flanges (Z of the bob bins. Each roller f extends across the frame driving all the bobbins in one row (see Fig. 9). The spindles of the bobbins are carried in eyelets If, preferably made of porcelain, and provided with a slot iv to allow of their insertion thereinto.

A thread guide K is provided for each bobbin d to direct the yarn thereto. The thread guides K are 'mounted in'rows on transverse rods K above the bobbins (Z each being capable of adjustment on its rod by the set screw F. The thread guide rods K are mounted at each end on longitudinal rods K carried on pivoted levers K so that by imparting a rocking motion to the levers K the rods K and with them the thread guides K are given a reciprocating movement over the bobbins d.

The shafts F are driven from the change speed gear box L controlled by the handle L through the shaft M on which are mounted worms M which gear with worm wheels 7 on the shafts F. The foremost shaft F is provided with a worm which gears with a worm wheel on a short shaft m on which is mounted a gear wheel m gearing with a wheel M mounted on the shaft M which carries a cam m The cam m engages with runners at on a cross shaped lever N pivoted at a so that as the cam m rotates an oscillating movement about the pivot n is given to the lever N. The upper end of the lever N is slotted at n and the end 0 of a connecting rod 0 is fixed in the slot M; The other end of the connecting rod 0 is connected to an arm K connected to one of the pivoted levers K so that as the lever N oscillates about the pivot n a corresponding oscillating movement is imparted to the lever K and the rods K and thread guides K are reciprocated over the bobbins cl.

The sizing roller B and the comb C are driven through the rope or belt 6 from a pulley f on the end of one of the shafts F.

The yarn passes from the bobbins a through the teeth of the comb B over the sizing rollers B through the teeth of the reciprocating comb C to the heated cell or plate C. The yarn comes into contact with a greater or less surface of the plate C according to the height of the roller B which is adjustable, the surface of the plate with which they are allowed to come into contact depending upon the nature of and thickness of the yarn, the speed of travel being varied by the gear box L.

After leaving the heated plate C and passing through the comb C the yarn is guided by the thread guides K to the bobbins d in the winding frame D.

What I claim as my invention and desire to protect by Letters Patent is 1. A yarn sizing machine of the type referred to comprising a series of bobbins from which the yarn is drawn off, a roller over which the yarn is passed to supply size thereto, a drying chest along which the yarn travels, a second series of bobbins on to which the yarn is wound, a frame carrying said series of bobbins, flanges on the ends of said bobbins, a plurality of rows of shafts extending across the frame between each row of bobbins, discs mounted on the shafts and contacting with the flanges of a pair of bobbins in adjacent rows so that each disc drives the bobbins by frictional contact therewith and means for driving the transverse shafts.

2. A yarn sizing machine of the type referred to comprising a series of bobbins from which the yarn is drawn off, a roller over which the yarn is passed to supply size thereto, a drying chest along which the yarn travels, a second series of bobbins on to which the yarn is wound, a frame carrying said series of bobbins, flanges on the ends of said bobbins, a plurality of rows of shafts extending across the frame between each row of bobbins, worm wheels carried by said shafts, discs mounted on the shafts and contacting with the flanges of a pair of bobbins in adjacent rows so that each disc drives two bobbins by frictional contact therewith, a plurality of longitudinal bars carried by the frame and bearings for the bob-bin spindles carried by the longitudinal bars, a shaft running longitudinally of'the frame and worms mounted on said shaft to gear with the worm wheels on said transverse shaft. 7

3. A sizing machine for artificial silk and analogous yarns of the type in which the yarn is drawn off one set of bobbins or cheeses and wound on to another set of bobbins or cheeses comprising the combination with a creel of bobbins mounted therein, a sizing trough adjustable as to height, means for raising and lowering the trough, a sizing roller mounted therein, a heated drying plate, a reciprocating comb at one end of the plate, a stationary comb at the other end of the plate, a winding frame, bobbins mounted therein, friction discs attached to said bobbins, a plurality of rows of shafts extending across the frame between each row of bobbobbins having slots therein of difierent depths to receive the spindles When the bobbins are in the operative and non-operative position respectively, thread guides for guid- 5 ing the yarns t0 the bobbins, reciprocating transverse rods to impart a rolling motion to the yarn on which the thread guides are mounted and means for giving a reciprocat ing motion to the transverse rods substantially as described. 10

In testimony whereof I have hereunto set my hand.

WILLIAM BICKERTON CROMPTON.
